Be it known thatI, MARK A. DEES, a citi zen-of the United States,residing at St. Louis,-

in the State of Missouri, have invented certain new andusefullmprovements in Freight- Cars, of which the following is aspecification,

.reference being 'had to theaccompanyng drawings, forming part thereof.'y

My invention relatesto freight-cars of the 1o class generally used fortransporting petroleum and other liquids or grain from place to place,such cars being commonly known as tank'or oil cars. i

yOne-object 'of my invention is to improve r 5 the construction of anoil or tank car,the body of which is ordinarily an elongated cylinder,for the purpose of increasing its carrying capacity without raising itscenterof gravity, lengthening its wheel-base, or the distance bezo tweencouplers. In accomplishing this result I make the body or cylindricalportion of the car of enlarged diameter and increase its I' lengthnntiliit extends from coupler to coup-Y ler. The tank or body of the carthus changed is supported onA .holsters on' the trucks yas low aspossible', bringing the footboard on top of i the tank to the level ofthat of the ordinary.;

y, box freight-car andthe bottom of the tank below the line of draft. 3oabout nine feet in diameter, if mounted on a platform or in any otherknown manner to permit the placing of-.the draft mechanism beneath itelevates the car and raises its cen-v ter of gravity so high that thedanger 'of de- 3 5 railment and overtnrningon roundingcurves is great.An increased height also endan gers the car by its liability to strikelow bridges, tunnels, &c. ,l overcome this`difticulty by lowering thesupports of the tank, as above 4o stated, and placing the sills vanddraft mechanism within the tank, but separated from its contents`by-means of a duid-tight fioor or` partition.

A further-featnre of my invention consists in placing within thecylindrical body of the `car a truss or open frame lrunning centrallytherethrough from end toend for the purpose of increasing its strengthand rigidity.

. Referring to the drawings, Figure 1 is a lon- 5o gitudinal sectionthrough a car constructed in accordance ywith the principles of myinvention. Fig. 2 is a cross-section thereof on L truck-bolster a.

The tank, which is Y the line 2 2. Fig. 3 is a horizontal sectiononthei'ine 3 3 of Fig. l. Fig. 4 shows a `modiied formv of the couplingmechanism; and Figs.P 5 and 6 are cross-sections therethrough 'on thelines 55 and 6 6, respectively. Fig..

7 is a view of a modified form of the floor.

Similar reference-letters indicate similar parts in the respectivefigures. A and B represent' two car-trucks of ordif l nary constructionsupporting a cylindrical tank or body C. Between the wheels of eachtruck and forming a part: thereofgis the usual Tothe under side of thetank or body lC, near each end, is bolted a crescent-shapedbody-bolsterc, each of which rests onone of the truck-holsters a and is pivotallyconnected thereto by a king-bolt b.v Side bearings d are applied to thetrucks and tanker car body as usual.` Y Q The cylindrical body or tankC, as it will be hereinafter designated, is closed at each end by a headD, made duid-tight in any approved manner. 1Within the tank and bolted75 Extending from' the floor F to the T-beam E 8o 'in the longitudinalcenter of the tank 'are a .Series of nprights' or columns Gwhich, withthe truss-rods H, reachingdiagonally between the uprights and thezeudsof the car, ,form a y tight and rigid truss-frame for strengthening thetank and retaining itin proper shape. turnlinckle Iris shown'on one' ofthe truss# rods for" adjusting its" tension. Y Similar buckles may beplaced on all the rods, if desired. I p

A tank constructed as above will be ver-y strong and rigid and welladapted to resist all strains to which it may b e subjected, especiallysuch as areproduced by supporti ng the tank near the ends only. g

Within the-tank, but beneath the floor F,

' are placed two longitudinal channel beams or sills J, projecting vashort distance through the head D of the tank and spaced suiciently Ifar-apart to permit the` application oit'l draft roo mechanism K betweenthem.. Thechannelbeams J, which are placed with their web portions invertical position, are riveted through their lower flanges to the bottomofthe tank, d

their upper llanges being connected to each other by ahorizontal plateL, riveted to the flanges and running the length of the car immediatelybelow the door F. This construction forms a strong box-girder, aordingadditional strength tothe tank and a central support for the oor F,which, however, is not connected to the channel-beams .I or plate L. Bysupporting the tank C on the trucks A B in the manner described itsheight is reduced to such an extent that notwithstanding its largediameter the footboard W on the top of the tank willrbe' substantiallyona level with the roofs of adjoining box-cars. The bottom also is lowenough topermit the line of draft to pass ywithin the tank, as shown anddescribed. I

v Instead of using a straight plate for the floor F it may be of theshape shown in Fig. 7 and by dotted lines inv Figs. 2 and 5 to closelyembrace the box-girder formed by the channel-beams J, 'plate L, andbottom of the tank.

Ordinary draft-rigging, such as that. shown in Figs. l and 3,4 willusually be employed to couple the cars togethergbut undersomecircumstances the through or continuous drawb'ar (illustrated in Figs.4, 5, andd) may be desired. In the continuous draft rigging here'represented the channel-beams J J are not rivetedto the tank, but areconnected at their tops by a continuous plate L and at their bottoms bytwo plates M' M', their inner ends being separated a short distance atthe center of the tank. The bottom plates MM' rest and are'adapted toslide upon the bottom of the tank. .A casting O', riveted to the bottomofthe tank at its center, extends upwardly betweengthe plates M' M' and-has alongitudinally-directed hole, through which a rod P' may freelyslide, the ends/of the rod P' being` secured to blocksQ', which latterare in turn fastened to the beams J J above the inner ends of the platesM' M'. ,A space is thus left on each side of the casting O' and betweenit and one of thel blocks Q', Within' which spaces are spiral springs-R' R', preferably surrounding the `rod P', to serve as bu'ffers. Thecontinuous draw bar thus constructed is capable of a slight longitudinalmovement under working conditions to lessen the force of shock and jar,which is conveyed toy the springs and there absorbed. Angle-pieces S'are rivetedto the tank C and floor `F to guide the draft mechanismv andretain it in its proper position. These angle- I pieces are dispensedwith when the Iiloor is made as represented in F ig.|`7.

I do not restrict myself tothe exa'ctdetails of construction,combination, and arrangemeut herein set forth, it being obvious thatvminor variations thereof not involving the exercise of invention maybemade bythe skilled mechanic, and'such departures from what is hereindescribed and claimed not-involving' invention I consider as within thescope and terms of my claims.
